In the blazer picture, with her hair swept up in a bun, I see that Jinger's got that little patch of hair on the front/side that doesn't grow. I have the same thing. It's not noticeable now that I have short hair, but I remember when I had long hair, I hated when I'd wear a ponytail or a bun and I had this patch of hair sticking out. It never grew longer than about two inches.
I don't think Jinger looks pregnant either.
